When it comes to app development, Apple, Google, and Microsoft all have very different strategies that align with their ownbusiness models. So with 2014almost over, we decided to take a look at the trios mobile app stores to answer a simplequestion: How much do the three develop for each others competing platforms?

As you might expect, Apple doesnt bother making apps forAndroid or Windows Phone at all.

Google loves Android and iOS, and it almost completely shuns Windows Phone.

Microsoft, meanwhile, has adopted a strategy of developing apps for all three platforms. It even offers more iOS apps than Google does. In fact, both Microsoft and Google offer more iOS apps than Apple does in its own store.

In 2015, we don’t expect Apple will significantly change its approach to competing platforms. We do look forward, however, to examining the state of the Microsoft’s platform after the Windows Store and Windows Phone Store merge. Will this push Google to start playing ball with Microsoft more?
